摘要

A 30/35 GHz dual-band phased array transmitter (TX) front-end is demonstrated in a 0.25um SiGe:C BiCMOS process. The front-end provides variable phase shifts from 0°~360° with a ~10° resolution. A 5-bit amplitude resolution is achieved for advanced beamforming algorithms. Accurate transmitted beam patterns can be generated by applying a genetic algorithm with the achieved phase and amplitude resolution. The front-end transmits a >+14dBm saturation output power with >+15dB gain and >+22dBm OIP3 at 30/35GHz.
